member are angularly disposed asindicated I a at 15, for a purpose to be hereinafter described. 'Pivotally secured to'the base 13 of the U-shaped member are links 16, and'said links 16 are arranged in spaced relation to each other.

Pivotally mounted in" ears 17 which project from the upper end of the supporting bed 10, is a U-shaped member 18, and the links 16 are coiled about the base of the member'18 as indicated b acter 19' in-Fig, 2. ne of these'1inks16 is provided with an extended end bent in the form of an operating handle 20, by means of which one of the links 16 may be rocked about its pivotal point on the U-shaped memthe reference char-v her 18 as will behereinafter more fully dei scribed; I

-As nioreclearly shown in Fig. 2, the rear face of the supportingbed 10' is provided end,"ajnd' nea its member '22.'-

The reference character designates fa corrugated or'otherwise 'roughened bar, and

said bar is providedwith oppositely disposed wings 24L, adapt'ed'to engage the "pairs of .with'spaced guide members 21, near its upper lower end by, a single gulde guide members 21 in order that the bar may be reciprocated upon the rear face oflthe,

supporting bed 10 As more clearly shown in- Fig; 5, thisroughenedbar, 23 hasa flat side which slides in engagement with the rear face of the supporting bed 10. Near its lower end the bar 23is provided with. a wing 25, adapted to slide beneath the guide member 22, and upon its sideopposite to the Wing I 25, is a Wing 26having an upstanding lug I 27; Connected to the upstanding lug 27 ,of

the wing 26,i's a coil spring 28, and said coil spring 2 8'is secured to one of the wings 50 as indicated by, the reference character 29.

By th'isj'con'struction, it will be apparent that asthebar' 23 is reciprocated, the coil spring 28 will be placed under tension a'nd'i-will serve'to'returnthe'b'ar'23 to normal position upon-release'ofthe'force. by which it is re ciprocated.

In order that the bar 23; may belre'cipr oli v cated,ian operating lever 30 is employed, and

mo I

said operatinglever-80 ispivotally mounted as at 31, in a yoke 32, pivotally mounted as at 33 upon'the angularlyi'disposed ends of the legs of the base member 11. This yoke member 32'is provided with an upstanding lug 34, and engaging said upstanding lug 34 is'the downwardly bent end 35 of a hook member 36. The opposite end 37 of this hook member is bent downwardly and rigidly secured as at 38 to the bar 23. "The lower end of the operating lever 30 is provided with an angularly disposed portion 39 adapted to engagethe basejof the upstanding lug 3 1 of the yoke member 32. -By this Y construction it will be seen that the operatingmember is free to move about its pivotal point 31 when rocked forwardly as shown in dotted lines in Fig. 3, but as shown by dotted lines in said figure, when the operating lever is pulled rearwardly, the angularly disposed extension 39 will engage the base of the upstanding lug 34 and will cause a rocking of the lug about its pivotal point 33 and cause a reciprocation of the bar 23.

In order to vary the length of stroke of the .reciprocations of the bar 23, the wedgeshaped member'LO is provided, and said wedge-shaped member is slidably mounted upon an upstanding lug 41, as more clearly shown in Figs. 1 and 4. By moving said wedge-shaped member 40 transversely of the supporting bed 10, it will be apparent that the downwardly bent end 37 of the member 36 will engage said wedgeshaped member and limit its rearward movement. By this arrangement, the stroke otthe bar23 is varied. l 1

Mounted on the rear face of the supporting bed 10 and having sliding movement in theguideway 12', is aparriage 50. I Pivotally mounted in this carriage, is a 'line marker 51, theends of said line marker'51 being bent around thesupporting bed and pivotally secured to the carriage as indicated by the reference character51. One of the legs of the line marker 51 is extended downwardly as indicated by the referenceschara'cter 53, and v pivotally secured to said downwardly bent endis a pivoted lever 54 cut out to provide a shoulder 55. Pivotally mounted on the carriage 50, as at 56, inears 57, is a pawl 58, and saidpawl is provided with a'cut-out portion 59, through which thefreduced end of the pivoted lever 5 1 passes. Tzhe end 61 of this pawl is adapted to engage the roughened portion of the reciprocating bar 23 as more clearly shown in} Fig. 4:, and the end 61 of said bar is maintained in engagementwith the roughened portion of thebar 23 by a-coil spring 62, one end of which issecured to the pawl '58 opposite the end 61, the other end being secured as at 64 to the carriage 50. V Secured to the upper end ofthe support I ing bed 10, is a ,U-shaped sheet metal memberr'O, which forms a clamp by means of which the manuscript copy is retained in position on the bed 10. 'The several leaves of a book or the like are adapted to be passed between the members of the clamp as shown in Fig. 3. i V The device operates in the following manner: j

TWith a book or other copy mounted on the supporting bed 10, the line marker 51 is positioned at the first line of 'writing on the manuscript copy near theupper end. of the sheet.

In order to accomplish this, the line marker 51 is grasped and rocked about its pivotal points 52. This operation causes a reciprocation of the; lever 54' through the medium of the downwardly bentportion 53 of the line marker, until the shoulder 55 of said lever engages the marker 51 permits the. pawl 56 to be moved about, its pivotal point until its end 61 engages the roughened portion of the bar'23, it being understood that the spring '62 serves to rock the pawl58 as heretobetore stated.

Assuming now thatthe operatingflever 30 be rocked about its pivotal point 131 until 7 its angularly disposed end 39 engages the base o't'lthe member 351 of the yoke30. Upon the completion oflfurther pressure of :the' operating lever 30, the yoke 32 will be rocked" about its pivotal point and through. the

medium of the hook member 36, will reciprocate the roughened bar 23. As the roughened bar 23 is reciprocated, the carria e, owing to the engagement of the end 61 o the pawl 58, will be moved relatively to the supporting bed 10, and the distance otmovement of said carriage 50 will be regulated'by the positioning of the wedge-shaped member 40.

From the foregoing it will be apparent that the present invention provides means whereby a manuscript copy Vmay be supported in convenient position'for copying,"

and, at the same time, a simple and novel mechanism for operating aline marker has been devised; Furthermore, theinvention provides a device of this character which maybe folded into a comparatively small space, together with new and novel-means foroperating the carriage spacing meohanism.
